Rh. timolis Trnr. (25 d, e) is at once discernible from the astreus-iovms, in the <$ by the short, round 
hindwing and the large discoidal spot on it. Head, neck and thorax yellowish-whitish-grey; the first 3 rings 
of the abdomen are yellowish mixed with pink, the last 4 rings carmine. Forewing whitish greyish-brown with 
a darker, large discoidal spot and a hyaline spot between the veins 3 and 7. Hindwing greyish-brown, at the 
costal margin lighter. abdomen quite carmine, wings lighter and faintly hyaline. Length of forewing: 27, 
$ 32 mm. Queensland (Australia). — papuana subsp. nov. (25 d) is much darker earth-coloured brown, and 
the $ has not such hyaline wings. New Guinea. 
Rh. crokeri Macleay ( = Amerila brachyleuca Meyr.). Anterior and middle legs chocolate-brown, 
tarsi carmine; posterior legs carmine; palpi carmine with 2 black rings; antennae blackish-brown with a red 
base; head, neck and thorax white, with 14 black spots; hindhead and tegulae margined with carmine; abdomen 
reddish-yellow, in the slightly, in the $ veiy intensely suffused with carmine. Forewing brown, the basal 
fifth white with 3 black dots, the disc of the wing between the veins 3 and 7, and a large spot in the cell-apex

subsp. nov. differs from the type by the unicolorously carmine abdomen in both sexes and the blackish greyish- 
brown colour of the wings. New Guinea. — novobrittanica Rothsch. differs from the type by the very much 
larger black spots of the head and thorax. Bismarck Archipelago. —- salomonis Rothsch. (25 d) differs from 
the typical race by the extremely large black spots of the head and thorax, by the broad, black interior margins 
of the shoulder-covers, and the blackish-brown forewings. Salomons Islands. 
Rh. nigropunctata B.-Balc. (25 d) differs from crokeri by the carmine, not white underside of the 
body, by the black, shaggily haired legs, the tarsi of which are only dotted red, the posterior ones being only red 
on the inside, by the absence of the red margining of the tegulae and by the fore wing being densely scaled brownish- 
black. The hindwing is unicolorously sooty blackish-grey with some white at the base. $ lighter, more blackish- 
grey. South East New Guinea. 
Rh. piepersi Snell. (25 e, f). Head whitish-grey; thorax brownish-grey, with one black spot each

Forewing hyaline greyish-white, the apical quarter, margins and discoidal spot drab. Hindwing hyaline greyish- 
white, with narrow drab margins, the anal angle prolonged to a lobe. $ with narrower, more pointed wings. 
Length of forewing: $ 27, $ 29 mm. Celebes and Sula Islands. 
Rh. eaudipennis Wkr. (25 d). Head, neck and thorax whitish pale greyish-brown with 8 black spots, 
the hindhead and inside of the tegulae margined with red; abdomen white with a carmine apex. Forewing 
drab, the terminal third and the discoidal spot darker, the disc between the veins 3 and 7 hyaline. Hindwing 
white, the apex drab, abdominal margin pale yellowish-grey. In the groove of the abdominal margin there 
is a very large pad of long, creamy-white hair almost covering the hindwing like a screen. The anal angle is 
extended into a long, pointed tail. $ larger, the abdomen carmine; the hindwing is drab as the forewing. Length 
of forewing: $ 20, $ 29 mm. New Guinea. 
Rh. lactea Rothsch. Forelegs outside yellowish ferruginous, inside dull carmine ; middle and hinlegs 
outside whitish, inside dull carmine; head and thorax brownish isabel-coloured, with 12 black dots. Antennae 
and abdomen carmine. Forewing lactean, with a hyaline disc. Hindwing semihyaline white. Length of forewing:

Rh. fumida Swinh. (26 f). Head and tegulae reddish brownish-grey, with 3 black spots, thorax darker 
greyish-brown, with one black spot each on the shoulder-covers; abdomen carmine. Forewing sooty blackish-

Vein 3 of the forewing rises rather far before the lower cell-angle; 5 above the angle; 6 from the upper angle; 
9 before 10 which is fused with 8 and forms a very long areola; 11 before the cell. Vein 3 of the hindwing
